A population-based, prospective cohort study. ⋯ High values of BMI may predispose to chronic LBP 11 years later, both in individuals with and without LBP. The association between BMI and LBP is not explained by an effect of LBP on later change in BMI.

Multicenter Study
Complications after 147 consecutive vertebral column resections for severe pediatric spinal deformity: a multicenter analysis.
Retrospective multicenter review. ⋯ A total of 147 consecutive pediatric VCRs performed by 7 surgeons demonstrated excellent radiographical correction. However, these complex reconstructions were associated with a 59% complication rate, thus emphasizing the challenging nature of these patients and procedures.

Prospective population-based cohort study. ⋯ One-fourth of the workers who received work disability compensation for a back injury self-reported reinjury after returning to work. Baseline variables in multiple domains predicted occupational back reinjury. Increased knowledge of early risk factors for reinjury may help to lead to interventions, such as efforts to reduce fear avoidance and graded activity to promote recovery, effective in lowering the risk of reinjury.

Comparative Study
Cyclic-RGD is as effective as rhBMP-2 in anterior interbody fusion of the sheep cervical spine.
Radiological and histological assessment of fusion status after anterior cervical discectomy and fusion (ACDF) procedure in a sheep spinal fusion model. ⋯ In this animal model the combination of cRGD and a mineralized collagen matrix showed superior fusion results in comparison with the mineralized collagen alone. Further, cRGD was comparably effective to rhBMP-2 in promoting interbody fusion by demonstrating less ectopic bone formations.

Biomechanical analysis of vertebral derotation techniques for the surgical correction of thoracic scoliosis. ⋯ Biomechanically, it is possible to significantly improve the correction of thoracic scoliotic deformities, particularly in the transverse plane, when using vertebral derotation maneuvers.
